Txhua yam uas yog a khoom muaj ib tug meej zoo thiab a meej ntim . Cov molecules hauv a khov kho nyob rau hauv qhov chaw ruaj khov thiab nyob ze ua ke. Txawm hais tias cov molecules tseem tuaj yeem vibrate, lawv tsis tuaj yeem txav los ntawm ib feem ntawm khov kho mus rau lwm qhov. Yog li ntawd, a solid ua tsis yooj yim hloov nws puab los yog nws ntim.
Ntxiv mus, dab tsi ua rau cov khoom muaj qhov tseeb thiab ntim?
Cov khoom muaj qhov ntim tseeb thiab puab vim particles a khov kho vibrate ib ncig ntawm qhov chaw ruaj khov. Cwj pwm ntawm Khoom : Cov khoom muaj qhov ntim tseeb thiab puab vim particles a khov kho vibrate ib ncig ntawm qhov chaw ruaj khov. Lub Kinetic Theory of Matter hais tias cov khoom ntawm cov khoom yog ib txwm nyob rau hauv tas li mus.
Tsis tas li ntawd, cov roj puas muaj cov duab thiab ntim? A gas yog ib yam khoom uas tsis muaj meej ntim thiab tsis muaj cov duab meej . Khoom thiab kua muaj ntim uas ua tsis hloov yooj yim. A gas , ntawm qhov tod tes, muaj ib lub ntim uas hloov pauv kom haum rau ntim ntawm nws lub thawv. Cov molecules hauv a gas nyob deb heev piv nrog cov molecules nyob rau hauv ib qho khoom los yog kua.
Tom qab ntawd, vim li cas cov khoom muaj qhov tseeb?
Molecules nyob rau hauv cov kua yog nruj nreem ntim thiab tuav ua ke los ntawm muaj zog zog ntawm attraction. Lawv muaj tsis muaj chaw nruab nrab ntawm lawv mus ncig. Qhov ntawd yog yog vim li cas cov khib nyiab muaj cov duab meej . - Vim tias cov atoms lossis molecules uas tsim cov khov kho tau ntim khoom ua ke.
Lub xeev twg muaj qhov tseeb?
Khoom

Dab tsi yog qhov txawv ntawm qhov pom tseeb qhov loj thiab qhov ntsuas qhov ntsuas qhov tseeb?
Dab tsi yog qhov txawv ntawm qhov pom tseeb thiab qhov tseeb? Pom meej qhov loj npaum li cas yog qhov ci ntawm lub hnub qub tshwm los ntawm lub ntiaj teb thiab nyob ntawm qhov ci thiab qhov deb ntawm lub hnub qub. Qhov loj npaum li cas yog qhov ci ntawm lub hnub qub yuav tshwm sim los ntawm tus qauv nyob deb
Cov khoom puas muaj ob qho tib si kinetic thiab lub zog muaj peev xwm?
Ib yam khoom muaj peev xwm muaj ob qho tib si kinetic thiab lub zog muaj peev xwm tib lub sijhawm. Piv txwv li, ib yam khoom uas poob, tab sis tseem tsis tau mus txog hauv av muaj lub zog kinetic vim nws txav mus rau hauv qab, thiab lub zog muaj peev xwm vim tias nws muaj peev xwm txav mus rau hauv qab txawm tias nws twb muaj lawm
Vim li cas qhov tseeb thiab qhov tseeb yog qhov tseem ceeb hauv kev tshawb fawb?
Qhov tseeb sawv cev rau qhov kev ntsuas ze npaum li cas los ntawm nws qhov tseeb. Qhov no yog qhov tseem ceeb vim tias cov cuab yeej tsis zoo, cov ntaub ntawv ua haujlwm tsis zoo lossis tib neeg yuam kev tuaj yeem ua rau cov txiaj ntsig tsis raug uas tsis ze rau qhov tseeb. Precision yog qhov ze npaum li cas ntawm cov kev ntsuas ntawm tib yam yog rau ib leeg
Yam khoom twg tsis muaj qhov ruaj khov thiab tsis muaj qhov ntim ruaj khov?
Cov theem ntawm cov teeb meem uas tsis muaj qhov ntim ruaj khov thiab tsis muaj qhov ruaj khov yog cov roj. Cov roj tsis muaj qhov ruaj khov
Puas yog lub khob ntim ntim muaj tseeb?
Volumetric Glassware Kawm tiav cylinders, beakers, volumetric pipets, burets thiab volumetric flasks yog tsib hom iav feem ntau siv los ntsuas cov ntim tshwj xeeb.Volumetric pipets, flasks thiab burets yog qhov tseeb tshaj plaws; cov neeg tsim khoom siv iav calibrate cov no mus rau qib siab ntawm qhov raug
